Specification of Letters Patent.

Patented Oct. 19, 1920.

Application filed August 9, 1919. Serial No. 316,471.

T 0 (Ill 10 7mm it may concern Be it known that I, CARI. MoDERMorT, acitizen of the United States, and a resident of Freehold, county ofMonmouth, and State of New Jersey, have invented a new and ImprovedElectrical Coin-Delivery hiachine, of which the following is a full,clear, and exact description.

This invention relates to coin delivery machines, and more particularlyto an electrically operated coin delivery machine.

An object of the, invention is to provide a coin delivery machine foruse in banks, merchandise establishments, and other institutions wheresilver coin is handled in making many change transactions.

It is a. purpose to provide a coin delivery machine consisting primarilyof a coin delivery unit electrically controlled by a key board unit, sothat the cashier or operator of the machine may be distant from the coindelivery unit.

It is an object to provide a coin delivery machine which will properlyfunction even though operated by unskilled persons. To this end themachine is so electrically controlled that the key board mechanism maybe engaged for a long period of time without damage to the mechanism orwithout obtaining more than one cycle of operation. Or the key board maybe instantly released, and yet the machine will complete its cycle ofoperation to deliver the correct amount of change. In fact, it is anobject to pro duce a coin delivery machine inherently simple andpositive in operation under all conditions.

A. special feature of the coin delivery unit resides in the provision ofmeans for automatically stopping the cycle of operation in case a coinbecomes jammed or clogged in the machine. This machine will eitherpositively deliver or eject all" coins simultaneously, or it will notdeliver any coins at all; in other words should one coin become cloggedduring the cycle of operation no delivery will take place, thus avoidingpossibility of incorrect change being made.

A special. feature of the machine resides in a release drive mechanismelectrically operated. This release drive is interposed between anelectric motor and the delivery mechanism and is employed to permit allparts to return to normal inactive position after one coin ejectingoperation has been completed.

Another feature of the coin delivery machine relates to a plurality ofjointly operat mg coin punchers operated simultaneously but separatelyselected to engage the coins of desired denomination in order that anyamount of change may be delivered.

A further feature resides in means for selectively lifting into positionthe desired coin punchers so that coin of required denominational valuemay be ejected by said selected coin punchers.

Further objects and features relate to a combined electrical andmechanical means for executing the positive delivery of the selectedcoins. To this end, there is employed a system of electro-selectivelyoperated devices directly controlled from the distantly located keyboard which is operated by the bank cashier or other person.

The above enumeration points out many of the important objects of theinvention, with reference to features of the mechanism. A practicalexample of a coin delivery machine is portrayed in the followingdescription, particularly pointed out in the appended claims, andillustrated in the accompanying drawings, wherein:

Figure 1 shows a perspective view ofthe coin delivery unit with thedelivery chute mounted thereon, and with a coin trough carried upon themachine. The coin delivery chute is arranged to deliver the coin on thefront side of the machine, while the coin trough has its back turnedtoward the front of said machine which places the coins carried in thetrough away from the customer who receives coins from the deliy'erychute. The coin chute may be extended through the cage of the cashiersotlice so the customer may readily receive the coin.

Fig. 2 points out a side elevation of the machine with the casing insection, or removed therefrom. as to disclose the machine parts of thecoin delivery machine.

Fig. 3 shows a back view of the machine, or a view looking" toward thecoins in the coin trough. This view is obtained by removing the rearwall of the casing. and shows the solenoid selector means employed toselect appropriate coin punchers, and shows parts of the drivingmechanism.

Fig. 4 shows a plan view of the machine with the casing removed. Thisview discloses the plurality of coin punching arms located above thesolenoid selectors, and the power motor with parts of the powertransmission.

Fig. 5 shows a fragmentary side elevation of the coin deliverymechanism. In this view the mechanism is in operation with a coin partlyejected from the trough ready to pass into the delivery chute.

Fi 6 shows a view similar to that of Fig. This is aside elevation, and afragmentary view. The deliverymechanism has undergone partial operationbut owing to the jamming of one of the coins the machine hasautomatically cut off its operation and is shown in a position ready toreturn to normally inactive position.

Fig. 7 shows a sectional view taken upon the line 7-7 of Fig. 5. Thisfigure relates to the mechanism employed for automatically cutting offthe operation of the machine in case a coin jams or clogs at the outsetof the operation.

Fig. 8 discloses a diagrammatic lay-out of the electric controllinsystem of the coin delivery mechanism. his figure shows the electricalcontrol elements connected with a preferred form of keyboard.

Fig. 9 shows a fragmentary detail view of the coin trough and ejectorhead mounted in guided relation with said trough, and Fig. 10 shows aview taken upon the line 10l0 of Fig. 9.

It is desirable to employ an effectively operating key board selectorunit with the coin delivery unit. To this end I have (lisclosed thedesign of a keyboard constituting an invention separate from the oneherewith presented. This key board selector unit is disclosed in anaiplication for patent filed in the United i tates Patent Office on the9th day of August, 1919, under the Serial No. of 316.470.

In the present application. andin Fig. 8, is shown a diagrammaticallayout of a bank of electrical contact bars which constitutes thesubject matter of the aforesaid application pointed out by the crossreference.

Tn constructing a machine under the specifications and claims of thisdisclosure, I employ an inclosed casing in which is mounted an electricmotor or other power means. A coin holder trough is mounted on the upperportion of the machine and provided with a number of grooves into whichthe cashier or operator will place stacks of coins arranged in order ofdenominational value. There is employed a plurality of jointly operatingcoin punchers which function to eject a single coin with each puncherfrom each stack' of coins. Filectro-selective means are employed foreach individual coin puncher in order that one or more punchers may belifted in position so as to eject a coin as it travels forward.-

Referring now more in particular to the views'for structural descriptionand operation, wherein the same machine parts are designated by the samereference chararters throughout, the numeral 1 points out a base fittedwith pads 2. The base is provided with a casing comprising side walls 3and a top 4:. A delivery chute is secured to the side of the machine andconsists of a tube 5 secured vertically to one side or face of the casinThe upper portion of this chute is open and connects with the deliverymechanism confined within the casing. while the lower portion of thetube curves outwardly in position to deliver coins to the recipient. Thecoin delivery opening of the chute is indicated by the numeral 6. Uponthe upper portion of the casing is fitted a coin trough 7. This cointrough is provided with a number of trough grooves cut in the facethereof into which are'placed stacks of coins. The coin trough willpreferably have about the same number of coin grooves or receptacles asthere are denominational values of coins in circulation. The trough 7will preferably be mounted on the machine in such a manner as to make iteasily removable to facilitate manufacture and assembly.

A pair of frames 8 are erected vertically on the base and spaced apart.Each frame is provided with a journal 9 integrally formed on the upperpart ofthe frame or leg members 8. The legs 8 of the frame are securedto the base by bolts or screws. The two journals 9 rotatably mount amain rock shaft 10. A. gear sector 11 is associated with the rock shaftand adapted to rotate therewith during operation of the machine; but soconnected as to move freely thereon should a coin become jammed during acycle of operation. The gear sector 11 is formed integrally with a hub12, the hub 12 being journaled upon the rock shaft. An arm 14 isintegrally formed with a hub, the hub being fixed upon the rock shaft 10by a pin 15 or other appropriate means. The, arm 1a and gear sector 11are positioned adjacent each other on the shaft with a little spliceleft between the arm and the gear sector. A stop pin 16 is fixed to thegear sector, and adapted to freely pass by the arm 14 in the space leftbetween the arm and said gear sector. The lower portion of the arm 1.4.is provided with a reach-bar 17, and on the outer end. of this'reach-baris made ahook 18. The reach-bar 1? lies adjacent the rim of the gearsector with the hook 18 turned back to engage the edge of said sectorand lying in contiguous relation therewith. Re

ferring to Fig. the arrow indicates the direction of rotation of theshaft10,-ai1'd it is seen that the gear sector 11 may rotate in thedirection indicated by the arrow without necessarily movingthe arm 14,but the arm it cannot move in the direction of the arrow withoutcarrying the sector with it due to positive engagement of the hook 18with the sector 11. A coil tension spring 19 has one end thereofconnected with the arm 14 and the other arm thereof connected to anadjustment rod 20. This adjustment rod is pivoted upon the forwardportion of the gear sector as designated by 21 and travels with thesector.v A boss 22 shown in Fig. 2, is made on the hub of the' gearsector, and in this boss is formed a hole in which is slidably mounted ascrew threaded member 23. This member is connected to the adjustment rod20 through a pivot pin 24. A nut 25 is employed to adjust the member 23back and forth in the boss 22. In this manner the adjustment rod 20 ismoved about its pivotal point 21, which tightens or loosens the spring19 according to the desired adjustment of the mechanism. The spring 19will have sufficient tension to confine the arm and gear sector injoined movable relation during the operation of the machine. but willhave sufficient resilience to permit the gear sector and arm to moverelatively one upon the other should any portion of the coin deliverymechanism become locked or clogged as hereinafter described.

A drive shaft 27 is employed to rotate the gear sector, and toaccomplish this a worm 28 is fixed to the drive shaft 27. The driveshaft is supported at one end thereof by a journal bearing 29. Thisbearing 29 is carried between a pair of lifting arms 30, said arms beingspaced apart and pivoted at 31 upon a support 32. The support 32 isfixed to the base 1 of the machine. The upper ends of the lift arms areprovided with a pivot 33 which permits the lift-' ing arms 30 to swingabout the pin 31 to slide the bearing 29 along the shaft 27. A solenoid34 is fitted with a guide tube 35, and a solenoid plunger 36 is slidablyconfined within the guide tube. The plunger is bifurcated at the endthereof and provided with a pivot pin 37 joined with a link 38. Theother end of the shaft 27 is fitted with a knuckle 39 which connectswith a universal joint formed in the end of a main shaft 10. This shaft40 is journaled in a standard 41 secured to the base 1. The shafts 27and 40 are, therefore, connected one with the other through a universaljoint which permits the outer end of shaft 27 to be swingable up anddown in order that the worm 28 may be engaged with the gear sector 11.The solenoid 34 and associate parts exercise a control over the shaft 27to en'- gage the worm with the gear sector. The views 5 and 6 show thegear sector and worm' in operative engagement. This engagement ismaintained by virtue of energization of the solenoid 34 which draws theplunger 36 inwardly to swing the shaft 27 upwardly until the worm andgear are engaged. This movement of the solenoid is executed against thetension of a spring 42. This spring has one end thereof connected to thebearing 29 and the other end thereof connected to the support 32. \Vhenthe solenoid 34 is deenergized the tension of the spring 42 actstoreturn all parts to normal position by pulling the bearing 29 outwardly on the shaft, which disengages the worm and gear sector, as shownin Fig. 2. The means of controlling the energization of the solenoid 34will form the subject of a later description within this specification.A sprocket 4a is fixed to -;the shaft 40. Means for transmittingrotation to the sprocket 44 and thus operating the above describedmechanism will now be described. An electric motor 16 is secured to thebase 1, and a sprocket 47 is fixed to the motor shaft. A chain 48 isconfined on the sprockets 44 and 47 to transmit rotation to the shaft27. The operation of the motor is controlled from a key board remotelylocated from the coin delivery unit, said operation being carried outwhen the circuit through the motor is closed by the operator to tieliver coins to the chute. In order to limit themotion of all parts, apair of stops 136 are fixed to the frame. A swinging arm 135 is fixed tothe shaft 10 with the lower end of said arm disposed between the stops136. These parts are shown in Fig. 2. When the swinging arm 135 hasengaged the uppermost stop the machine rests supported in that positionuntil another cycle of operation is carried out. A pin 137 is fixed tothe shaft 10. and a tension spring 135 has one end thereof attached tothe outer end of the pin 137, and the other end thereof attached to thebase or some part of the frame so as to draw the mechanism intorearwardly limited non-operative position against a stop 136. The springacts to hold the machine in inactive position ready to undergooperation. When the machine undergoes a complete cycle. the swinging arm135 engages the lowermost stop 136. which stops the travel of themachine in that direction sin'iultuncously with the disengagement of theworm 28. which permits the spring 138 to return the parts to normallyinactive position. The above complete description covers the assembly ofparts from the motor through the transmission to the shaft 10.

llpstanding arms 50 are fixed to the rock shaft 10. The arms 50 arespaced apart and preferably fixed to shaft 10 near each end of saidshaft. A rod 51 is fixed in the upper ends of the arms 50. The parts 50and 51 mount a plurality of coin punch arms employed to selectivelyeject the required amount of coins from the machine. The several coinpunchers are designated by the reference characters 5, 10" and 10", 25and 50. These coin punchers consist of a rod one end of which is fittedinto a hub extension 52, shown in Fig. 4, said hub extension beingintegrally made with a bearing 53. The bearing 53 is journaled on therod 51 which permits the coin punchers to pivot thereabout. On the freeend of each coin puncher is fixed an ejector head adapted to engage acoin as the coin punchers travel forward. This member consists of afinger 54 inte rally formed with a guide 55, as shown in Figs. 9 and 10.Since each coin puncher is pivoted on the shaft 51, the ejector headsmay be raised or lowered into operative engagement with the coins in thetrough as later seen.

A guided relation exists between each ejector head and the coin trough7. The

coin trough 7 is provided with a coin support plate 57 which is fixed tothe lower edge of the upstanding trough member 7. The coin plate 57 isprovided with a slot 58. The slot 58 is approximately the width of thefinger 54 of the ejector head, and said ejector head is slidablyconfined in slot 58. The upper face of the guide 55 moves contiguouslywith the underneath face of the coin late 57. A coin ejector slot 59, asshown in ig. 2 isformed in the lower portion of the trough just'abovethe coin plate 57. Coins may be punched through the slot 59 by the coinpunchers, as later seen. The aforedescribed chute 5 passes through thecasing and a coin chute 60 is mounted adjacent the lower portion of thecoin trough. This coin chute 60 opens directly to the coin slot 59. Thedelivery chute 5 and the coin chute 60 are connected so that a coinwhich drops into the chute 60 will pass directly to the delivery chute5. Thus the chutes 60 and 5 connect together to form a continuous tubular member through which the coin passes until it is discharged at themouth 6 of the delivery chute. In order to hold the coins in positiveposition prior to the ejecting operation there is employed a retainingball 61, as shown in Fig. 9 which is movably confined in a bore formedin the trough memher. A spring 62 is placed in the bore back of the ballto press the ball normally downward into engagement with the upper faceof the coin plate 57. This retaining ball 61 is mounted forward of'eachcoin groove and prevents a coin from passing through the slot 59. \Vhen,however, a coin is thrust forward under the ejecting impulse'of a coinpuncher the ball 61 will be displaced u'pwardly, which permits said cointo be ejected through the slot 59.

As above described, means is provided to hold the coin punchers andejector heads in operative engagement within the coin plate. To this endsolenoids are employed to lift each coin puncher upwardly until thefinger 54 is in line with the rim of the coin. Fig.

2 shows the ejector head in downward posi- I tion prior to being liftedin line with the coin. Fig. 5 shows one coin puncher in upwardy limitedposition engaged with the rim of a coin and ready to eject said coinfrom the coin trough into the chute 60.

A number of solenoids designated in the drawings by 64, 65, 66, 67 and(58 are individually placed under each coin puncher and function to liftthe coin punchers into operative punching position. These solenoids arerespectively arranged to operate the coin punching members 5, l0 and 10,25 and 50. Each solenoid consists of an electro magnetic coil fittedwith a tubular guide 70. The tubular guide 70 projects from the lowerend of the magnetic coil 69 and passes through a hole formed in ahoriz'ontalsupport tube 71. This tube 71 is disposed between the twoframe legs 8, .and

as a part of the frame upon which the device is assembled. The'tube 70is provided with a solenoid plunger 72. The upper end of this solenoidplunger is fitted with an insulating head 73 which is fixed to the upperreduced end of the plunger 72. This head is provided with a shoulderwhich seats against the upper end of the tube and thus limits thedownward movement of the solenoid plunger. The lower portion of theplunger 70 .is knurled or grooved. This provides a roughened orirregular cylindrical surface. A hole is drilled through the tube 71 andthe guide 70. These-holes register one 'with the other, and a lockinghead 74 is slidably mounted in the registered holes with the forward endthereof in aposition capable of frictionally engaging the knurledsurface of the plunger 72. The head 74 is provided with a stem 75 uponwhich is con fined a coil compression spring 7 6. A shaft 77 ishorizontally pivotally arranged between the two support frames 8. Thisshaft 77 has fixed thereto a depending arm 78, and in the lower portionof this arm is provided a hole 79. The outer end of the stem 75 isloosely retained in the hole 7 9 with the spring 76 confined on the stembetween the arm 78 and the head 74. Thus as the shaft that the liftingarm 80 may be actuated to control the engagement of the locking head 74with the plunger 72. The compression spring 76 will be so adjusted thatit will hold the head 74 at rest in the tube 71 without engaging theknurled plunger,-this,being the normally inactive position of parts. Theabove description is directed to one of the solenoids employed forcontrolling the lifting operation of the coin .punchers. Each solenoidis provided with the plunger and locking means as described. The shaft77 and the lifting arm 80 are common to all of the solenoids, while anindividual arm 78 is employed for each separate solenoid so that theplungers of all solenoids will be locked when the machine is inoperation, and released when .the machine has completed its work.

An upstanding rod 83 is fixed in the shaft 10, and adapted to move withthis shaft. The upper end of this rod is shaped to function as a cam tolift the arm 80. The rod 83 has a horizontal bend 8% as shown in Fig. 4right angular with-the body 83, and the bend 84 is shaped on an upwardcurve as shown at 85 as shown in Fig. 5. The upwardly curved extremity85 is arranged in line with the finger 81. A rod 86 is integrally madewith the lift arm 80. This rod 86 is arranged approximately verticalwith the upper end thereof reduced in size and bent over in the form ofa hook and welded to the lift arm. The upper end of the rod 86 is shapedin the form of a hook so as to space said rod apart from the arm 80 inorder that the cam 85 may have freedom of movement in its backward andforward direction to engage and disengage the lift arm 80. The lower endof the arm 86 is bifurcated to receive the upper end of a solenoidplunger 87. The upper end of the plunger 87 is flattened and slotted, asshown in Fig. 2, and slidably confined in the furcation' of the rod 86.A pin is employed to attach the rod 86 and plunger 87 together. The slotallows slight lateral motion of either member in order to avoid crampingof parts during operation. Thisplunger 87 is slidably confined in asolenoid 88. This solenoid is supported on a post 88; Vhen energized thesolenoid will discharge the plunger 87 upwardly to lift the arm 80 sothe finger 81 will be above the cam 85. Thus when the arm 80 is liftedin upward position the cam in its forward travel will engage theunderneath side of the finger 81 which thrusts the heads 74 against allof the solenoid plungers. When this operation takes place all of theplungers 72 are clamped irrespective of their position. All or a part ofthe plungers 72 may be in an upwardly limited position or may be down,and in either case they are clamped and held during the time thesolenoid 88 is energized while the shaft 10 is traveling in its cycle ofpartial rotation.

A bracket 90 as shown in Fig. 5 is fixed to the base and mounts a yoke91. A solenoid 92 is mounted in the yoke 91, and a solenoid plunger isslidably carried within the solenoid and guided by the yoke. Thesolenoid core consists of a plunger 93 mounted on an iron rod 94, saidrod provided with a weight 94 fixed to the lower end thereof. Theplunger is fitted with a brass rod 96 upon the upper end of which ismounted a fiber head 97. It is preferable to employ brass for the rod 96while iron will be used for the rod 94. This will cause the solenoidcore to properly function by moving upwardly when said solenoid coil isenergized.

The solenoid just described is employed to automatically break or openthe main circuit after said motor has completed its cycle of operation.To this end, a switch comprising contact bars 98 and 99 is mounted on afiber base 100. The bar 98 is pivoted on the insulating base, while thecontact bar 99 may be fixed to said base. Each contact bar is providedwith contact heads, and the one member 98 is somewhat longer than itscompanion contact bar, which arrangement positions the head 98 of thesolenoid directly un-. derneath the end .of the circuit breaker member98. A lever 101 is pivoted upon the fiber base and one end thereofremains in normal engagement with the underneath face of the head 98. Bypivoting the lever 101 the contact head 98 will pivot the switch part 98upwardly and away from the switch part 99 breaking the electricalcircuit main as later seen. A circuit breaker arm 102 is fixed to therock shaft 10, with the outer end thereof disposed in line with theouter end of the lever 101. lVhen the rock shaft 10 rotates, the circuitbreaker arm 102 tilts the lever 101 so as to thrust the solenoid plungerand head 98 upwardly to part or break the circuit switch 9899. Themechanism just described functions as a mechanical circuit breaker andcomes into operation simultaneously with the completion of the coinpunching action of the machine.

An auxiliary means is employed for opening the circuit breaker orcircuit parts 98-99 in case a coin jams or in case the machine does notproperly function. In order to accomplish this a circuit breaker arm 104as shown in Figs. 2 and (3 is pivoted on the frame at 105. Acounterbalanced weight 106 is attached to the circuit breaker arm 104 tokeep the bifurcated end 107 in upwardly limited position. The refer encenumeral 105 designates a shaft or rod which is horizontally j ournaledin the frame by having one end thereof journaled in the standard 41,while the other end thereof is journaled in the bracket 90. The circuitbreaker arm 104 is fixed to one end of this shaft 105, while the otherend of the shaft is provided with a breaker arm 108 as shown in Fig. 4which has its outer end bent in the form of a lift finger 109, said liftfinger ter- 20 said arm in case there is relative movement pin impingesthe arm 112.

minating in a position under and forward of the pivotal point of thelever 101 as shown in Fig. 6. Thus when the shaft 105 is partiallyrotated by swinging the circuit breaker arm 104., the arm 108 tiltsupwardly the lever 101 which thrusts the head 97 against the circuitbreaker 98 thereby opening the circuit. A depending rod 110 is'pivotally mounted at 111 on the arm 14. The numeral 111 designates apin fixed to the depending rod and pi'votally mounted in the arm 14. Theinner end of the pin 111 is 'rovided with an arm 112 fixed thereto. heparts 110, 111 and 112 comprise a swinging member, the upper portion 112of which is mounted on the inside of the arm 14, while the lower member110 is mounted on the outside of the arm 1 1 and freely swings about thepivot. The arm 112 is mounted in line with thestop pin.16 so that saidstop pin will engage between the arm 14; and gear sector 11.

llhe mechanism described in the preceding paragraph provides a safetycircuit breaking means whiclris automatically brought into use in case acoin jams. By referring particularly to Fig. 6 it is seen how that coinpuncheris engaged with a coin which has become jammed in the trou 'h andfails to eject through the slot 59. hen this occurs, which occasionallywill, due to bent coins or other irregularities, the gear sector 11moves forward under the driving impulse of the electric motor, and beingfreely journaled on the shaft 10 does not move the coin punchingmechanism. The coin punchers are moved only when the arm 14 is carriedforward during rotation of the gear sector, and since the coin punchersare locked against movement the spring 19 undergoes tension andstretches until the stop This throws the depending rod 110 forward totrip the circuit breaker arm 104: which opens the motor circuit therebystopping said motor; The worm gear will be disengaged and the spring 19cause the parts to return. to normal inactive position. When the wormdisengages the sector, the hook 18 on the reach-bar stops the movementof the gear sector, and the spring 19 is so adjusted to remain undersufficient tension to cause the hook 18-t0 continuously engage the faceof the gear sector. Thus the gear sector and the arm 141 are joinedtogether through the spring 19, which spring forms a yieldable'connection between the transmission and the coin punching mechanism.This yieldable connection prevents damage and breakage of parts when themachine fails to function due to jamming of coins or other imperfectfunctioning. During normal operation, and when the coins are readilyejectable from the machine, the spring 19 is sufficiently strong to movethe arm 14 along with. the

gear sector when said sector undergoes rotation.

The electric motor circuit, and other circuits necessary to energize theseveral solenoids employed, are under direct control of the operator.When a selected key is depressed the motor circuit and appropriatesolenoids become energized, The electric motor must necessarily undergoone complete operation, or cycle, in order that the coins will bepunched from the trough and ejected through the chutes. The operator mayoccasionally hold the key down to close the circuits sufiiciently longto complete the cycle of operation, but quite often the operator mightfail to hold said key down sufficiently long to complete the operation.Means are provided for automatically bringmg into operation anindependent circuit which furnishes current to the motor until saidmotor has completed its cycle of operation. This independent circuitfunctions regardless of the length of time the operator holds down thekey. 1

To this. end there is employed a relay 114, as shown in Figs. 3 and 41.This relay is supported on a suitable bracket 115. The relay moreclearly appears in the diagrammatic view of Fig. 8 where theelectromagnet is shown with a contact head, and an armature pivoted at116. The armature 117 1s prqvided with a weight so as to keep thisarmature and contact head normally disengaged from the contact head onthe electromagnet 114 when said magnet is deenergized. The upper portion118 of the armature is also provided with contact points and joins withthe main supplyline through a circuit 131 employed to furnish current tothis machine. The circuit wire 131 con- 105 nects with the relay magnet114, and also connects with the relay armature. The other end of thiscircuit wire 131 connects with an electric current main 121 whichsupplies the motor. Therefore, when the relay 11 15 in closed position,as shown in Fig. 8, the current from the battery 119 flows to the motorthrough the independent circuit wire 131 which furnishes current to thedisengaged from the circuit bars, then the current will flow to themotor through the wire 131. Therefore, if the operator releases the key95 before the cycle of operation is completed, the relay 11 1 andindependent circuit 131 functions to supply the motor until theoperation of the machine has been completed.

A battery or other source of current 119 supplies the main circuit line120. This circuit line 120 connects with a key board.

'Another section of the current main is the electric current main 123,this electric circuit 124 has connected in series therewith the electricmotor 46. A circuit wire 125 connects in parallel with the motor supplycircuit 124, said circuitwire 125 joining with the solenoid 88 toenergize same during the time the motor runs. Likewise'the solenoid 34connects in parallel through the circuit'wires 126 to the motor circuit124.

A key board is employed for fiperating the coin delivery mechanism. hiskey board comprises a plurality of contact bars which are fitted withsuitable keys so that the operator may depress the appropriate key inorder to close the circuit through the proper electro control elementsso that the correct number of coins may be discharged from the chute. Aground plate 127 is provided with a plurality of key elements. One ofthe key elements is shown in Fig. 8 and designated by 95. This keycomprises the button 95 formed on the upper end of the rod 128. Thenumber 95 printed on the button indicates the amount'of change whichwill be delivered when the button is depressed, and the key board willbe provided with a number of keys ascending in value in multiples of 5to 100. Hence the operator may deliver change as desired from one fivecent piece up to one dollar.

Contact bars 5 are employed in the keyboard and connect with the circuitwire 64. The several contact bars-5 are, therefore,

' connected directly to the solenoid 64 which controls the operation ofthe coin puncher 5. A bridge 5, diagrammatically shown, joins theseveral contact bars 5", and the circuit wire 6 1 connects to thebridge.

A number of contact bars 1O are shown and joined together by a bridge10, and the circuit wire 65 connects to-the bridge 10 This arrangementplaces the solenoid 65 in electrical connection with the bars 10".

A number of contact bars 50 are used in the key board and joinedtogether by a bridge 50, and the circuit wire. 68 is connected with thebridge 50. This places the solenoid 68 in electrical connection with thecontact bars 50".

A number of contact bars 25* are shown in the key board joined togetherby the bridge 25. This bridge is in direct electrical connection withthe solenoids 67 through the circuit wire 67.

Thus the key elements shown in Fig. 8 are arranged in groups, each groupbeing connected to its individual solenoid inorder that said solenoidmay be energized to lift. the coin puncher if current'flows from any oneof the bars of that particular group. The rod 128 is disposed betweentwo vertical banks of contact bars. The rod is provided with contactballs'or points which engage the desired contact bars. In this instancethe key is designated by 95 which in fact means that 95 will bedelivered from the coin punching mechanism when said button isdepressed. In order that 95 in silver be delivered it will be necesarythat the mechanisin deliver one 50 piece, one 25 piece. and two 10pieces. To this end. the key rod 128 is fitted with contact balls orpoints which will engage two of the 10 contact bars, and one of the 25contact bars and finally one 50 contact bar. hen the key is depressedinto position shown the con- .tact points engage said bars thusconnecting up the solenoids 65, 66, 67 and 68 with the key board. Therod 128 transmits the current from the ground plate 127 upwardly todistribute said current through the various contact bars. The electriccurrent main 120 connects with the ground plateand feeds upwardlythrough proper contact bars until the desired solenoid-s are energizedto lift the proper coin punchers into operative position. The key androd 128 in Fig. 8 are shown depressed so that the contact balls areengaged with the bars. The lower end of the rod 128 may have fixedthereto one end of a coil spring. not shown, while the other end of saidspring is fixed to the plate 127. A tubular casing .130 is fixed to theground plate and may have the spring above referred to concealed withinsaid tube. This 116 arrangement of parts will cause the key rod 128 toremain normally upward when in inactive position, since the coilcompression spring will function to return the rod 128 upwardly anddisengage the contact balls as 123 soon as the operator releases thebutton.

A plurality of contact bars 16 are also em loyed in the key board andjoined toget ier by abridge 46. The motor circuit wire 12 1 is connectedto the bridge 16. 125 This places the motor 46 in series with the keyboard and electric current main 120. The rod 128 also has a contact ballwhich engages one of the bars 46*, and when so engaged the current istransmitted upwardly 130 from the plate 127 through the bar 46, throughthe bridge 16 to the motor, and thus completes the circuit through theelectric current main to said motor.

A circuit wire 132 connects with the electric current main 122, saidcircuit 132 including the solenoid 92 in series therewith. This circuit132 connects with contact bars 92". The key rod 128 is fitted with acontact ball which will engage the contact bar 92" when said key isdepressed to start the machine in operation. Thus the solenoid 92 is inseries with the key board and electric current main. The contact bars92* are preferably somewhat deeper than the other contact barsconstituting the key board. This provides a longer. contacting area onthe contact bars 92 than is provided on the other contact bars. The bar92" has its bottom edge even or in the same plane with the bottom edgesof the other contact bars which causes the upper edge to be spacedsomewhat above the upper edge of the narrower bars. Thus when the key isdepressed a contact ball engages the bar 92 before any of the other barsare engaged. This action causes instant energization of the solenoid 92slightly prior to the energization of the other electrical elements ofthe system. Likewise this construction causes the solenoid 92 to be thelast member denergized means 102 impinges downwardly on the lever 101which thrusts the plunger 93 upwardly against the magnetic pull of thesolenoid coil 92. At this instant of operation, the plunger 93 firmlyadheres to the upper portion of the solenoid coil due to the magneticattraction thereof, and due to the fact that the plunger 93 has beenforced upwardly past the magnetic center of the solenoid. Thus thecircuit breaker 98 is held in upward and open position due to themechanical breaking of said circuit when the breaker arm 102 impingedthe lever 101.

The foregoing paragraph described the operation of the machine when thecashier or operator holds the key 95 down for a longer period than isnecessary to cause the machine to function. It often occurs that anoperator may press the key downwardly and hold the circuit closed, andin such case itbecomes necessary that the circuit be mechanically brokenin order that the machine will not undergo a repetition of coin punchingactions. The mechanical circuit breaking means, consisting of theelements 98, 101, 102, and others. are specially employed for thepurpose of opening the circuit and stopping the electric motor when theoperator inadvertently and unnecessarily holds the key down. After thebreaker arm 102 impinges upon the lever 101, said arm 102 will return tonormal position and release the lever 101. Even though the lever 101 isreleased the lifting head 97 will remain in upward position and keep thecircuit 122-123 broken, due to the continued energization of thesolenoid 92 as long as the operator holds the key down. Thus the meansdescribed will positively prevent the machine from functioning more thanone time. Even though the operator holds the key in depressed positionlong after the coins are 'delivered, the machine Wlll not undergooperation again until the key is released and punched for another coinejection movement.

A partial description of the operation of the coin delivery mechanismhas been given. A complete recitation of the simultaneous energizationof the various solenoids and other electrical elements will now be takenup. It will be assumed that the machine is in inactive position and thebutton 95 in Fig. 8 is depressed to discharge 95 in silver to a customerthrough the chute 6. Instantly the key goes downwardly, the contactpoint on the rod 128 engages one of the circuit bars 92 which energizesthe solenoid 92 and attracts the plunger 93 downwardly so as to securelyhold the head 97 out of engagement with the circuit breaker 98. When thekey 95 has been depressed, the circuit wires 65, 66, 67 and 68 arebrought into direct electrical connection with the electric current main120. This action energizes the solenoids 65, 66, 67 and 68, since saidsolenoids are connected to the battery through the wires 122 and 123.The energized solenoids instantly discharge their plungers upwardly andlift the coin punchers 10 and 10, 25" and 50 into position within theslot of the coin plate. The rod 128 also engages the contact bar 46"which closes the circuit through the electric motor 46 and starts sameto running. Simultaneously with this action, the solenoids 3-1 and 88are energized. When the solenoid 34 is energized, the worm 28 is engagedwith the gear sector 11, and likewise the solenoid 88 functions to liftthe arm 80 upwardly so that the cam 85 may engage the finger 81. Themotor is now running, which causes the gear sector to travel forwardpulling with it the arm 14c. The arm 14 rotates the shaft 10 whichcauses the coin punchers to move forward in their respective slots inthe coin plate until the rim of a coin is engaged.

taining ball 61 which moves upwardly from the path of travel of the cointhus permitting the coin to be ejected into the chute 60.

Thus four coin punchers have moved for-.

ward and two 10 pieces, one 25 piece, and one 50 piece have been ejectedinto the chute 60. The 95 button was not provided with a contact ballwhich closed a 5 contact bar, hence the solenoid 64 was not energizedand a 5e piece was not ejected.

When the button 95 was depressed, the current was passed through therelay 114 which attracted the armature 117 to close the contact heads onthe member 118. This action on the part of the relay 114- closed theinde pendent circuit 131 from the battery to the motor. Thus currentsupplied directly from the battery to the motor, and the sole-' noidswhich were energized at the time the button was depressed. In case theoperator released the key 95, the operation of the mechanism will not bediscontinued. The

motor, therefore, runs until the circuit is mechanically broken. Theopening or breaking of the circuit is effected through the circuitbreaker means hereinbefore described consisting of the circuit breakerarm 102.

Assume now that a bent coin becomes jammed or clogged, which preventsthe machine from functioning. If one coin clogs, none of the coins willbe ejected; because if one coin puncher is prevented from completing itpunching movement, all coin punchs ers will likewise be prevented. Themotor will complete a few revolutions even though the coin is jammed,and run until the stop pin 16 travels forward to engage the arm 112which swings the depending rod 110 into engagement with the bifurcatedmember 104. This rotates the shaft 105, which thrusts the breaker arm108 upwardly against the lever 101 and thus breaks or opens the circuit.This causes the motor to stop, and at the same time the solenoids becomedei nergized. which allow all parts to return to normal position readyfor the next cycle of operation. The operator may then punch the buttonagain or will remove the coin which failed to eject.

It is seen that two means are provided for controllin the circuitbreaker switch 98*99. Lpon each-completed operation of the machine andafter the coins have been punched therefrom, the arm 102 functions tobreak the circuit, and this function is not dependent upon any action onthe part of the operator; since the independent circuit 131 immediatelyconnects the motor with the electric current main and excludes the keyboard so that the motor might run until the arm 102 moved down toimpinge the lever 101.

The key board is provided with a pluralityof keys variously numbered soas to secure any desired selection of coin punchers to be lifted intoupward position. Any one or all of the coin punchers may be lifted byselecting the proper key and depressing it to close the circuit throughthe electrical elements as described.

The coins are in a horizontal position in the coin trough, and whenejected fall on their edges or rims. They roll down the inclined chuteon their rims and finally drop vertically through the chute 5, wheredelivery is made at 6. This prevents the coins from sticking as theypass through and from the coin chute.

This machine is adapted for use principally in banks, department stores,theaters, and many other institutions where coin must be rapidly handledto make change for customers.
